The launch of the euro has made sex cheaper in Berlin. Prostitutes were quoted on Wednesday saying that they were opting for a two for one exchange against the German mark. This represents a price cut of a little over 2 percent.

That's about 1.36 euros cheaper than if the mark's official exchange rate was applied.

It appears that not all of Germanys sex trade is in agreement. A hidden price increase has emerged on Hamburg's Reeperbahn, the country's most famous red-light district. The Bild newpaper is reporting that the price of a 100 mark session has gone up to 60 euros - an increase of 17.35 percent.
